Abstract
This thesis examines the thermal environment and control system for the Polar Communications and Weather (PCW) satellite system as proposed by Telesat. The Telesat-PCW will use a unique orbit, based on the Tundra orbit to provide continuous meteorological and communications coverage to the Arctic region. The Telesat Tundra Orbit (TTO) was selected as it can meet the mission requirements using systems designed for Geostationary Orbits (GEO), a mature and robust field. However, the unique combination of communications and meteorological payloads, coupled with a previously unused orbit, presents an unexamined thermal design scenario. Using an existing geostationary satellite design for PCW would significantly reduce costs. This thesis describes the spacecraft thermal environment of the TTO, compares it to the thermal environment of the geostationary orbit, and numerically analyzes the suitability of a typical geostationary satellite thermal design system for PCW by using a Thermal Mathematical Model (TMM). The analysis shows that a thermal control system for a typical GEO communications satellite can sufficiently regulate PCW spacecraft temperatures in the TTO.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
